Les TIC i la sostenibilitat
Alier Forment, Marc; López Álvarez, David; García Almiñana, Jordi; Sánchez Carracedo, Fermín
El segle XX va ser el segle de moltes coses, però, en particular, va ser el segle de la globalització. Es van globalitzar l’economia, les guerres, la cultura...; en
general, es va globalitzar tot allò relatiu a l’activitat humana i fou, en part, a causa del naixement de la societat de la informació. ‘Societat de la informació’ és un concepte que fa referència a una transformació que està experimentant la societat des de la meitat del segle XX, una societat en què s’observa una transició d’una economia basada en els béns materials a una economia basada en el coneixement. En aquest nou context econòmic i social, les tecnologies de la informació i la comunicació (TIC) ocupen un espai central. La societat de la informació és vista com a successora de la societat industrial, per això s’empren també els termes ‘societat postindustrial’, ‘postindustrialisme’ o ‘era de la informació’.

A participatory service learning process for FOSS-based solidarity projects
Franquesa Griso, David; López Álvarez, David; Navarro Moldes, Leandro; Sánchez Carracedo, Fermín
Software and information and communication technologies (ICT) can be key elements for social development, especially in developing countries. Projects on ICT for development (ICT4D) are an important tool to incorporate positive changes in these communities. However, as with other technologies, ICT and particularly software supporting social processes have a huge potential for change, and for replication to many of these communities, but also a huge potential for disruption. From experience in over 50 ICT4D projects, we have learned how important it is to design and implement an open and participatory process based on the service
learning (SL) concept, where different forms of learning, service and free and open source software (FOSS) become natural and interdependent parts of social development. The lessons learned help us in designing sustainable processes for positive change supported by FOSS that can be appropriated by indigenous communities, contributing to their social development and social justice.

Evaluación formativa usando exámenes no presenciales
López Álvarez, David; Sánchez Carracedo, Fermín; Cruz Díaz, Josep Llorenç; Fernández Jiménez, Agustín
Los exámenes tradicionales están orientados a la evaluación sumativa, no a la formativa, y provocan un aprendizaje superficial, más que un aprendizaje profundo. Su objetivo es evaluar, no facilitar el aprendizaje. Los estudiantes perciben que su futuro a corto plazo depende de su nota en un examen, por lo que orientan su estudio a aprobar dicho examen. En este artículo se exponen las ventajas e inconvenientes de realizar un examen no presencial, con evaluación sumativa y formativa, que los estudiantes realizan fuera de clase a lo largo de un periodo de tiempo mucho más largo que el de un examen tradicional, lo que les ayuda a conseguir un aprendizaje profundo.

Marco para el desarrollo de la competencia transversal "Comunicación Eficaz"
López Álvarez, David; Ramírez Bellido, Alejandro
Hay bastante consenso entre los profesores y los empleadores sobre la importancia que tiene para los ingenieros saberse comunicar. También hay consenso respecto a las bajas
capacidades comunicativas de nuestros titulados. Esto provoca que la competencia transversal “Comunicación eficaz” sea vista como imprescindible en nuestras titulaciones. Pero, al igual que otras competencias transversales, nos falta base
teórica para definir en qué consiste la competencia y cómo trabajarla (y evaluarla). En este trabajo se propone un marco de referencia para desarrollar esta competencia en los estudios superiores de Ingeniería Informática, aunque puede aplicarse a
otras ingenierías.

Using a crowdsourcing knowledge base to support the sustainability and social compromise skill in computer science engineering studies
Alier Forment, Marc; López Álvarez, David; Sánchez Carracedo, Fermín; García Almiñana, Jordi; Piguillem Poch, Jordi; Velasco Becerra, Martha Elena
The Skill "Sustainability and Social
Commitment" is commonly accepted as essential in today's world. However it proves tricky to introduce into the curriculum, mainly because of lack of knowledgeable teachers. To address this issue we present a knowledge base that brings together scientific articles, books, videos, compilations of data, experiences, etc., related to sustainability and knowledge areas associated with computer science engineering. This is a valuable tool that should provide to the teacher accurate
and useful information in the research task of finding links between her course and the "Sustainability and Social Commitment" skill.

In addition to he technical skills, the new trends in engineering education include the so-called professional skills. These skills are usually hard to teach and to evaluate, and some of them are difficult to include in technical subjects. In this paper, we analyze the "Sustainability and Social Responsibility" skill, an we present several techniques to develop it, both at the comprehension and the application levels according to the Bloom taxonomy. Besides, we also analyze the main requirements in an Educational Institution in order to implement this skill. / En los nuevos planes de estudios hay que desarrollar competencias que resultan novedosas: prácticamente no han sido trabajadas con anterioridad. Cómo enseñarlas y cómo evaluarlas es una preocupación para los diseñadores de los nuevos planes. Este artículo analiza la competencia "Sostenibilidad y Compromiso Social", explicando técnicas para desarrollarla tanto a nivel de comprensión como al de aplicación, según la taxonomía de Bloom, y analiza las condiciones que deben darse en un centro para poder implementar estas técnicas en las asignaturas de su plan de estudios.

A survey of sustainability promotion experiences: the IPSO Project
García Almiñana, Jordi; García-Almiñana, Daniel; Esteban Álvarez, Francisco; Pujadas Garriga, Marta; Navallas Ramos, Francisco Javier; Miralles Marsa, Ramon
Purpose: This chapter presents the first results of an international survey taken through the IPSO project initiative. The objective of this survey is to identify the
experiences of other universities about initiatives to enhance the recognition, support and incentives for teaching and researching in Sustainable Human Development.
In addition, the study envisages the identification of staff motivation mechanisms in those universities for an increasing integration of the sustainable
development at the academic work.
Design/methodology/approach: The survey was sent to approximately 150 universities from all over the world. The form had fourteen short questions, but included some requested open comments and links in order to facilitate an exploratory analysis of the web pages and a deep study of the different areas tackled by the document.
Findings: It was possible to observe that many universities are performing a good job on promoting sustainability. Although most initiatives developed by universities are related to incentives, this does not mean that incentives are more important than the adoption of criteria or recognition policies. Incentives are easier to implement than strategies that require a deeper change. However, to be effective, they should be part of a clear and global strategic university policy.
Originality/value: This work aims to initiate or improve the dialogue between the
existing sustainability initiatives at the universities interested in this topic, providing useful information for a debate about measures and incentives for the teaching and research activities.

A HW/SW codesign-based reconfigurable environment for telecommunication network simulation
Noguera, Juan José; Badia Sala, Rosa Maria; Domingo Pascual, Jordi; Solé Pareta, Josep
Sequential network simulation is a high time-consuming application, and with the emergence of global multihop networks and gigabit-per-second links is becoming a challenging problem. A new approach to this open problem is presented, based on HW/SW co-design. A complete modular and scalable reconfigurable system architecture is
explained. Most important features of this simulation framework are: (1) efficient and flexible network simulation, and (2) transparent use of the reconfigurable system by telecommunication networks engineers because of the use of a high level network modeling language.

Performance impact of the grid middleware
Carrera Pérez, David; Guitart Fernández, Jordi; Beltran Querol, Vicenç; Torres Viñals, Jordi; Ayguadé Parra, Eduard
The Open Grid Services Architecture (OGSA) defines a new vision of the Grid based
on the use of Web Services (Grid Services). The standard interfaces, behaviors and schemes that are consistent with the OGSA specification are defined by the Open Grid Service Infrastructure (OGSI). Grid Services, as an extension of the Web Services, run on top of rich execution frameworks that make them accessible and interoperable with other applications. Two examples of these frameworks are Sun’s J2EE platform and Microsoft’s .NET. The Globus Project implements the OGSI Specification for the J2EE framework in the Globus
Toolkit. As any J2EE application, the performance of the Globus Toolkit is constrained by the performance obtained by the J2EE execution stack This performance can be influenced by many points of the execution stack: operating system, JVM, middleware or the same grid service, without
forgetting the processing overheads related to the parsing of the communication protocols. In the scope of this chapter, all this levels together will be referred to as the grid middleware. In order to avoid the grid middleware to become a performance bottleneck for a distributed grid-enabled application, grid nodes have to be tuned for an efficient execution of I/O intensive
applications because they can receive a high volume of requests every second and have to deal with a big amount of invocations, message parsing operations and a continuous task of marshaling and unmarshalling service parameters. All the parameters of the system affecting these operations have to be tuned according with the expected system load intensity. A Grid node is connected to to other nodes through a network connection which is also a decisive factor to obtain a high performance for a grid application. If the inter-node data transmission time overlaps completely the processing time
for a computational task, the benefits of the grid architecture will be lost. Additionally, in many situations the content exchanged between grid nodes can be considered confidential and should be
protected from curious sights. But the cost of data encryption/decryption can be an important performance weak that must be taken into account. In this chapter we will study the process of receiving and executing a Grid job from the perspective of the underlying levels existing below the Grid application. We will analyze the different performance parameters that can influence in the performance of the Grid middleware and will show the general schema of tasks involved in the service of an execution request.

SLA-based resource management and allocation
Guitart Fernández, Jordi; Macías Lloret, Mario; Rana, Omer; Wieder, Philipp; Yahyapour, Ramin; Ziegler, Wolfgang
The aim of the chapter is to describe how service-level agreements (SLAs) could be
utilized to provide the basis for resource trading based on economic models. SLAs
enable a service user to identify their requirements, and a provider to identify their capabilities. Subsequently, the terms in an SLA are necessary to ensure that
mutually agreeable quality is being delivered by the provider according to the
agreement. The use of service-level agreements (SLAs) in a resource management
system to support Grid computing applications is described. To this end, we provide an architecture that supports the creation and management of SLAs. The architecture of the system, in terms of the components and their interactions, is first
presented, followed by a description of the specific requirements for a marketoriented
Grid economy. We use SLAs as a means to support reliable quality of service for Grid jobs. The creation of such an SLA requires planning and orchestration mechanisms. We will discuss these functionalities and also consider the economic aspects such as dynamic pricing and negotiation mechanisms. These mechanisms are necessary to enable SLA formation and use, and to ensure that an
SLA is being adhered to during service provision.
